STEAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 786,273, dated April 4, 1905.

Application filed August 21, 1902. Serial No. 120, 169.

To u/ZZ whom, it new concern:

Be it known that I, JOSEPH G. DUCK, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Steam-Separators, of which the following is a specification, reference being had to the accompanying draw ings, forming a part thereof.

This invention relates to apparatus for separating water, oil, or other liquid from steam. Its main objects are to break up the steam and bring all its particles into contact with metal surfaces without materially increasing condensation, reducing live-steam pressure, or increasing back exhaust-stean1 pressure, to conduct the water, oil, or other liquid immediately upon its separation from the steam out of the direct course of the steam, and thereby prevent its reuniting therewith, and generally to improve the construction and operation of apparatus of this class.

It consists in certain novel features of construction and in the arrangement and combinations of parts hereinafter particularly described, and pointed out in the claims.

' In the accompanying drawings like letters designate the same parts in both figures.

Figure l is a vertical medial section of a separator embodying my invention, and Fig. 2 is a cross-section of the same on the line 2 2, Fig. 1.

a is a casing, preferably cast in the form of a cylinder, which is arranged vertically and provided at the upper end with a central steam-inlet connection Z) and at the lower end with a steam-outlet connection a. This outlet connection is extended by a short pipe (Z above the bottom or the lower head of the separator-chamber. Between the inlet and outlet connections the separator chamber or casing is formed or provided With a series of alternating circular or central and annular catch-basins e, f, and g, arranged horizontally and concentrically with the casing one above another. The lower catch-basin g is formed with a depending rim or flange h, extending around and below the upper end of the outletpipe d. An outwardly and downwardly projecting shield "Z is attached to the outletpipe d below the rim h. A drain-tube 7' extends downwardly from the center of the upper basin 6 through the opening in the annular basin f into the basin g. Drain-tubes Z5 extend downwardly from the lower catchbasin 9 through the shield L, and drain-tubes Z extend downwardly from the annular catchbasinj, opening at their lower ends into the upper ends of the tubes Zc. A shield m is placed over the upper end of the drain-tube j in the upper basin e.

n is a discharge-pipe which is provided with a valve (not shown) for drawing off the water or other liquid caught in the lower part of the separator-chamber.

The several catch-basins are preferably cast integral with the casing a. The lower head of the casing is preferably made separate and detachable, while the other head may be cast with the body of the casing.

A sight-glass 0 is attached to the lower part of the casing to indicate the level of the liquid, which should not be allowed to rise above the shield i. The drain-tubes Z are of smaller diameter than the tubes 70, so that they can be passed through the threaded openings for the latter in the basin 9 and screwed into the bottom of basinjl- The lower ends of the tubes Z are preferably tapered and made to project slightly into the upper ends of the tubes Zr, as shown.

The separator herein shown and described operates as follows: Steam entering through the inlet connection Z) strikes the upper basin 6 and is deflected outwardly thereby, passing over and around its upturned rim through the annular space between it and the wall of the separator-chamber. It next strikes the annular basin f and is deflected thereby inwardly over its inner rim. Passing downwardly through the central opening in the basin f, around the central drain-tube j, the steam is directed into and against the last catch-basin g, by which it is again deflected outwardly. It passes thence downwardly through the annular space between said catch-basin and the casing, below and around the depending rim 7L, thence upwardly and inwardly into the opening in the upper end of the outlet-pipe d. The water, oil, or other liquid caught in the upper catch-basin and upon the shield m is conducted down through the tube out of contact with the main body of steam into the lower basin g, and the liquid caught in the annular basin f flows downward through the tubes Z and is discharged into the upper ends of the tubes 7c, entraining with it the liquid caught in the lower basin g. Thus all the liquid as it is separated from the steam is conducted oil out of contact therewith and ultimately discharged into the lower part of the separatorchamber below the shield i, which separates it from the steam flowing around the lower edge of the rim 7L into the outlet-pipe. In its passage through the separator the steam is alternately separated and reunited, all its particles being brought into contact with metal surfaces on which the entrained liquid is deposited. A thorough separation is thus effected with the least possible expansion and condensation of steam.

Various changes in minor details of con struction may be made within the spirit and intended scope of the invention.

I claim- 1. In a steam-separator the combination of a chamber having inlet and outlet connec tions one above the other and alternating, central and annular basins arranged one above another between the inlet and outlet connections and having drain-tubes leading downwardly therefrom, the drain-tube of the upper basin extending through the basin beneath it and into the basin next below, and a shield over the upper end of the drain-tube leading from the upper basin, substantially as described.

2. In a steam-separator the combination of a chamber having a steam-inlet connec tion at the top, a steam-outlet connection leading out above the bottom and a liquiddischarge connection leading out at or near the bottom, alternating central and annular catch-basins arranged one above another between said steam inlet and outlet connections and having downwardly-extending draintubes, and a shield surrounding the steamoutlet connection above the bottom of said chamber, substantially as described.

3. In a steam-separator the combination of a cylindrical chamber having central vertically-disposed steam inlet and outlet con- .nections one above the other, the outlet connection leading out of said chamber above the bottom, and alternatingcircular and annular catch-basins arranged concentrically in said chamber one above another between said inlet and outlet connections and having drain-tubes extending downwardly therefrom, the drain-tube of the upper basin extending through the basin beneath it and into the basin next below, and a shield over the upper end of the drain-tube leading from the upper basin, substantially as described.

4. In a steam-separator the combination of a chamber having steam inlet and outlet connections arranged one above the other, the outlet connection opening out of said chamber above its bottom, and alternating central and annular catch-basins arranged one above another between said connections and having drain-tubes extending downwardly therefrom, the lower basin having a depending rim extending below the opening into the outlet connection, substantially as described.

5. In a steam-separator the combination of a chamber having steam inlet and outlet connections one above the other, the open ing into the outlet connection being above the bottom of said chamber, alternating central and annular catch-basins arranged one above another between said connections and having drain-tubes extending downwardly therefrom, the lower basin having a rim which extends below the outlet-opening, and a shield extending outwardly from the outlet connection below said rim, substantially as described.

6. In a steam-separator the combination of a cylindrical chamber having central steam inlet and outlet connections one above the other, the opening into the outlet connec tion being above the bottom of said chamber, circular and annular catch-basins arranged one above another between said connections, a shield extending outwardly from the outlet conneetion below the lower basin, a draintube extending downwardly through the cen tral opening in the next annular basin into the lower basin, a shield over the upper end of said tube, drain-tubes extending downwardly from the lower basin through the shield below it and drain-tubes extending downwardly from the intermediate annular basin and opening at their lower ends into the upper ends of the drain-tubes of the lower basin, substantially as described.

In witness whereof I hereto al'fix my signa ture in presence of two witnesses.
